Which PSU for i5 3470 and HD7850

[senkeiser]

Hey guys,

I'm looking for a reliable PSU than can power efficiently a Core i5 3470 and Gigabyte HD7850.
My budget is around 70-80$

is Corsair CX600 great?

Thanks

Hi. The CX600 is not bad but you don't need that much. The XFX ProSeries Core Edition 450W will do fine for you. Even the 650W version is currently cheaper than the CX600.

Thank you! Is the XFX 450W reliable? I didn't heard anything about them..

It's made by SeaSonic based on their S12II platform which also makes PSUs for Corsair.

For a system using a single reference clocked Radeon HD 7870 GHz Edition graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 28 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

The XFX ProSeries 450W (P1-450S-X2B9), that johnsonjohnson specified, only has one (6+2)-pin PCI Express supplementary power connector.

You would have to go with the XFX ProSeries 550W Core Edition (P1-550S-XXB9). Although the XFX 650W Core Edition (P1-650S-NLB9) is selling for the same price after rebate as the 550W model at the moment.

The Corsair Builder Series CX600 ( SKU# 75-001668 / CP-9020048 ), with its maximum combined +12 Volt continuous current rating of 46 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 650 Ti.

I thought the OP said Gigabyte HD7850 which requires only one connector? The OP can go with the 550W or 650W for future upgrades if he wants.

Sorry. My mistake.

No problem; I thought I made a mistake for a moment there. 😉
